I have waited about a year to provide a review of the MCH-6 four stage, gas powered, 4,500psi, breathable air compressor in order to provide a better review after fair usage and to see how it holds up.
Here is what I have gathered after almost a year of use.
Firstly, at a price tag of $3,000 it certainly isn't for everyone. That price does NOT include freight shipping. Overall it weighs 84 pounds. Quite manageable for one person but much easier with two. It is 31" x 14" x 15" so it doesn't take up much space which is a plus for me as I hardly have enough room with all my other toys and equipment around.
It is powered by a 5.5 HP Honda four stroke gasoline engine that is quite efficient with fuel. I have used it countless times and have only used 1-1/2 tanks of fuel. This is running at full throttle while filling. The engine is quite loud at 87DB so ear protection is recommended especially in areas that are not wide open outdoors. I use it under my car port and the sound definitely reverberates from the metal roofing. The engine is very easy to start using the pull cord but needs to be choked when initially started, and for longer periods in cooler and cold weather. The engine has an hour meter that also monitors RPM of the engine. The hour meter is useful as it requires the compressor lubricant be changed every hundred hours of use.
The actual compressor is an Italian Coltri 4 stage 4,500 psi with air quality of "DIN 3188-CGA Grade E-NFPA 1500- EN 12021", whatever that means!!! In other words, breathable air suitable for air guns. It takes approximately 19 mintues to fill an 80CF tank from 500 to 3,000 psi. The condensation drains are both manual and should be drained every 20 minutes of operation to ensure quality air. They are easy to open and close and very accessible. The air intake is at the end of a long tube that is easy to manage to ensure that no exhaust gets into the intake which could contaminate the air. The fill hose is high quality high pressure hose and comes standard with a DIN300 adapter with pressure release valve. The DIN fitting can easily be swapped out for a paintball adapter for direct fill of an airgun or pony tank at the cost of losing the pressure release valve. This could be addressed by making your own from parts at any HPA outlet online. The compressor can be ordered with either a 3,000 PSI pressure release valve or a 4,500 PLV depending on what applications you use it for.
Now for my thoughts. Although I was a bit nervous about spending this kind of money on something just for my own use, it has almost already paid for itself with fuel savings and time saving from going to a paintball facility to fill my tanks. This is great as the field has reduced it's pressures in it's cascade tanks to 4.200psi to prevent blowing out the burst discs on clients paintball tanks. So getting a full fill was virtually impossible without driving 2 hours somewhere else.
The system is extremely easy to use and maintain. I have had no problem moving it around by myself and have even lifted into the bed of my lifted truck by myself without any strain. This also makes it easier for me to move it into the shed to secure when not in use. I generally refill my 88CF SCBA tanks when they reach 2800-3000 psi. It takes about 7 minutes to fill one tank from 2800-4500. Much faster than a shoebox or many other portable compressors on the market these days. There is no external air needed other than the air we are breathing right now which is a plus seeing as how there is no need for another compressor to feed it like the boosters require. I have been using a lot of air since I started shooting the big bore PCPs and have a couple buddies that also use PCPs living close and we use the system on a regular basis.
My overall opinion of the system is that if you are looking for a fast, portable compressor. It's ease of use is superior and the quality of the components is also superior. I would certainly recommend it to anyone that could budget it. I love this thing!
The only change I would make would be a better muffler on the engine to reduce the noise emission.
Overall, 5 of 5 Stars.

Very nice compressor !!!
-
Thanks Wayne. I saved up for several years to buy it and am certainly glad I did!
-
thank You for this Review Matt!
I have been looking at the two available models from DayState, which are Coltri compressors re-branded. One of them is actually less costly than the Omega Turbo Charger. Hummmmmm!!!

You're quite welcome. They are certainly excellent quality Mike. Performance is superb so far.

Clarksville has turned into a cesspool unfortunately..... Had I not been stationed at Ft. Campbell when I retired I would be elsewhere for sure! Plan on moving to south TN within the next three years. Pretty country down that way.
-
Thanks for the detailed and excellent review on this compressor. Very well done and thorough. It surely is nice to own a reliable compressor that gives you full fills without the hassle of dealing with a dive shop.
-
Thanks Matt, good to know as I have been slowly rebuilding a Max Air, which is yet another rebrand name for the Coltri. Daystate, Max Air, Nuvair, ..all the same compressor. Here is the pic of mibe when I got it....super crusty.

I just checked, as this didn't sound right to me. The Nuvair is made in China, and is a copy of the Coltri. The Daystate "is" a Coltri.
Coltri is made in Italy, and has been making dive compressors used the world over for a lot of years. ;)
Not to mention, the Daystate badged Coltri is substantially cheaper, with top notch support.

Dunno where you checked, but the parts I bought from Nuvair in California are genuine OEM Coltri parts. https://www.nuvair.com/products/compressors/hp/mch6-portable.html (https://www.nuvair.com/products/compressors/hp/mch6-portable.html)
I know there is a Davy copycat made in China and I inquired as to the parts interchangeability with the China vendor on Amazon. The answer i received was "not exactly"

I found new Nuvair compressors on Amazon. Says shipped from China. Says Nuvair, but marked Davi. You tell me?
Something fishy going on here. LOL
Very glad to see that the actual Nuvair is not chinese! Is there anything the
Chinese don't clone? LOL

Ah I see! I didn't look closely at the Davi pictures, as I was interested in a top end rebuild kit. Definitely gotta do your research nowadays. Mystery solved :)
-
Michael I think they clone just about anything they can get their hands on. Several years ago Whites Electronics started putting $2 bills right into the finish on the bottom of their gold metal detectors because the Chinese were cloning ones that looked identical on the outside but weren't anywhere near as good as the U.S.A. made one.
-
Lot's of fake Coltris out there unfortunately. Just have to be careful what you purchase I guess. Imagine thinking that you are getting a true Coltri and end up with a Yong Heng or the like. Not putting down the Heng, but for the cost, oh man I would be livid!

A little TLC and I bet it will be good as new.
-
It will be worth the time and effort! ;)
-
I agree.
-
The last thing is I am trying to avoid buying a new case...one of the cylinder studs broke off (she locked up) so am dealing with that now. All of the case tolerances seem to be ok, but ad to buy a new crank, rod bearings and a host of other parts. Trying to keep it under $700 for the entire project...we will see!
I have most of the parts, just need the time to get it finished up.
-
Well lets hope that you can get her going with what ya have now instead of chucking out more dough!

Me either! Well for now I can at least use the filter setup with my Chinese compressor, so if it doesn't work out it isn't a complete loss. Got this all set up a while back but haven't used it yet. Want to video the first usage.

Nice. Gotta love re appropriation!
